Brazil Nuts Effects on Selenium Status and Cognitive Performance
Brazil Nuts Effects on Selenium Status and Cognitive Performance
NCT ID: NCT02121457 Phase: NA Status: COMPLETED Enrollment: 31 Completion: 2012-08
Conditions
Mild Cognitive Impairment
Interventions
Brazil nut, selenium
Summary
Some studies reported that selenium status is associated with cognitive function. However only a few reports have investigated whether selenium supplementation can benefit cognitive performance and in most of them selenium supplementation was not exclusive. Also, none of those reports have used foods rich in selenium as a source of supplementation. Thus, the aim of our study was to investigate whether the consumption of Brazil nuts improves cognitive function. We hypothesized that the daily consumption of Brazil nuts would have benefits on selenium status, increase antioxidant enzyme activity and improve cognitive function in older adults with MCI.
Primary Outcome
Selenium level in plasma and erythrocyte
